Management Strategy for the Chaw Pass, Rainbow, and Butte FiresMost fires occurring in the Greater Yellowstone Area are caused by lightning. Yellowstone National Park is a fire-adapted ecosystem. Fire plays an important role in maintaining the health of the area’s wildlife and vegetation. Firefighters are monitoring the fires from the ground and from the air. These three fires are being managed in order to protect people and property, enhance the area’s natural resources, and effectively use available firefighting resources. The National Weather Service forecast for the next several days calls for clear skies, no rain or snow, and light winds with highs in the 60s and lows in the 30s. These weather conditions could prompt some increased fire activity and fire growth late in the afternoon on into the early evening.
